You need to ensure that your work is original and not plagiarized. Plagiarism is a serious offense in the publishing world. Additionally, some publishers may require you to have a synopsis of the story, which should briefly summarize the main plot, characters, and the overall concept of the light novel. It's also advisable to have a few sample chapters ready in case they request it. The cover design, although not always required at the submission stage, can also be a factor in getting your light novel noticed if you can provide a professional - looking concept.
Typically, the manuscript should be in a proper format, such as double - spaced text with a standard font. The length might be restricted, say between 50,000 to 150,000 words for a typical light novel. And it should have a clear and engaging plot.
One important requirement is that your light novel should have a unique selling point. This could be an original setting, a fresh take on a common theme, or a set of really interesting characters. Also, the language should be accessible and not overly complicated. Publishers often look for light novels that can appeal to a wide range of readers. So, avoid using jargon or overly technical terms unless it's relevant to the story. Another aspect is the marketability. They will consider if there is a potential audience for your light novel, so it's good to research the current trends in the light novel market.
